Good Points
With upgraded (expensive at the time) memory card the map capacity seemed good, including parts of Europe.

Bad Points
As general comments above.

General CommentsTOMTOM GO 510Was always unreliable from new. Kept locking up. Poor battery life. When turning on it would take a long time to pick up the satellites - up to half an hour - I could find my destination before the tomtom even started. Sometimes the voice directions did not match the screen images (images correct, voice not).

At just over a year old the freezing up became even more common, reset stopped working and it does not even turn on now.
